Oracle存储过程中提示“权限不足”的解决办法
Oracle存储过程中提示ldquo;权限不足rdquo;的解决办法
我们知道,用户拥有的role权限在存储过程是不可用的。如:
SQL> select * from dba_role_privs where grantee='SUK';
GRANTEE GRANTED_ROLE ADMIN_OPTION DEFAULT_ROLE
------------ ------------ ------------ ------------
SUK DBA NO YES
SUK CONNECT NO YES
SUK RESOURCE NO YES
--用户SUK拥有DBA这个role
--再创建一个测试存储过程:
create or replace procedure p_create_table
is
begin
Execute Immediate 'create table create_table(id int)';
end p_create_table;
--然后测试
SQL> exec p_create_table;
begin p_create_table; end;
ORA-01031: 权限不足
ORA-06512: 在"SUK.P_CREATE_TABLE", line 3
ORA-06512: 在line 1
--可以看到,即使拥有DBA role,也不能创建表。role在存储过程中不可用。
--遇到这种情况,我们一般需要显式进行系统权限,,如grant create table to suk;
--但这种方法太麻烦,有时候可能需要进行非常多的授权才能执行存储过程
--实际上,Oracle给我们提供了在存储过程中使用role权限的方法:
--修改存储过程,加入Authid Current_User时存储过程可以使用role权限。
create or replace procedure p_create_table
Authid Current_User is
begin
Execute Immediate 'create table create_table(id int)';
end p_create_table;
--再尝试执行:
SQL> exec p_create_table;
PL/SQL procedure successfully completed
--已经可以执行了。

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values and pointers to data rows, and is suitable for non-primary key column queries.
